Correct Answer: B

Rationale: The correct answer is B: Provisions for adequate hydration and pain management. In managing a sickle cell crisis, it is essential to provide adequate hydration to prevent further sickling of red blood cells and ensure proper pain management to alleviate the severe pain associated with the crisis. While information for parents and home care may be important aspects of overall care, they are not specific to the immediate medical management of a sickle cell crisis. Administration of iron supplements is not recommended during a sickle cell crisis as it can potentially worsen the condition by promoting the production of more sickled red blood cells. Adequate oxygenation is crucial in sickle cell disease, but factor VIII is not typically part of the management of a sickle cell crisis.

Correct Answer: D

Rationale: The correct answer is D. A left extremity capillary refill greater than 5 seconds indicates poor blood flow to the extremity, which is a sign of compromised circulation. This finding requires immediate intervention by the nurse to prevent complications such as tissue damage or necrosis. Choices A, B, and C are important assessments but do not indicate an immediate need for intervention like the delayed capillary refill in choice D.

Correct Answer: C

Rationale: Placing the client in an upright position during meals is the correct intervention to prevent aspiration in a client with Parkinson's disease. This position helps facilitate swallowing and reduces the risk of aspiration. Choice A is incorrect because encouraging the client to eat quickly can increase the risk of choking and aspiration. Choice B is not the best option as straws may not prevent aspiration effectively. Choice D is incorrect as thin liquids can actually increase the risk of aspiration in individuals with swallowing difficulties.

Correct Answer: B

Rationale: Drug overdose is the most common method of attempted suicide. While hanging, gunshot, and slashing the wrists are also methods used in suicide attempts, statistics show that drug overdose is the most prevalent method chosen by individuals attempting suicide. Hanging, gunshot, and slashing the wrists are indeed common methods as well, but drug overdose ranks highest in terms of frequency.

Correct Answer: D

Rationale: Elevating the head of the bed 60 to 90 degrees is the correct intervention to facilitate proper placement of the NG tube. This position helps to use gravity to guide the tube smoothly into the gastrointestinal tract. Soaking the NG tube in warm water (Choice A) is not necessary for proper placement. Inserting the tube with the client's head tilted back (Choice B) can cause discomfort and may lead to improper placement. Applying suction while inserting the tube (Choice C) is not recommended as it can cause trauma to the nasal passages and esophagus.
